If you have the sensors unplugged, then 16.2 is a good target. I got 25 mpg in my GN (not stock...) at 70 mph, with the A/C on. I was running about 16.2
I had some occaisional bucking, but the plug wires are about shot...

so im thinking about pulling the 02's and then dailing in the tune again. have you seen any negative feedback from this? i'd love to get 25mpg at 16.2, but dont want to ruin my daily driving by not having o2s in.
also is it hard to dail in the tune without 02's i heard that the idle and cruise needs lots of attention to maintin at a constant value.
